my kwa m16 project gun
« on: May 23, 2008, 01:56:56 pm »
i got all the parts figured out but i just want to run this by you guys

kwa 16
12v 4200 battery
sw computer mosfet
element light poly piston 2nd and 3rd teeth removed
sp140 or sp 170
then short stroke it down to right under 400 fps
6.01 dbc barrel 509mm
fire fly hop up bucking

lookin for 390~ fps at 40 rps

sr-15 front


PTW's are just like Ferraris. Look great, cost tons of money, and can be completely dominated by things half the price

I wish I could afford BF3. I buy groceries and illegal slave-children instead.

With that setup, you're looking at a magical exploding gearbox that does about 500FPS for half of a magazine.

YOu can get 395 out of an SP120 and a featherweight piston, easy, but you'll benefit from an overbored cylinder. THe 6.01mm barrel is likely to cause you trouble outdoors, when you'll suddenly find that temperature and humidy cause you jamming and accuracy problems.

A monster 9.6v battery will run you at a more than adequate ROF with high-speed gears (won't need high-torque gears with a 120% spring), and a 10.8v might be more than you need, but with anything less than a ratbuster spring and high-speed gears to match, you won't need a 12-volt.

How long have you had the basic gun for?

Because currently, I'm drawing 390FPS at about 1350RPM out of an M4, and I can assure you, I'm only using a 9.6 and an M110 spring.

Never attribute to malice that which is adequately explained by stupidity.

i would short stroke it down to 400 fps but now im thinking of just doin that with a sp120
the guns not out yet
the 6.01 is for making up fps if i lose to much while short stroking it
and the 12v is to get up to near 40 rps

Dont get a 6.01 for it those only work good in bolt action/ semi auto only guns. also get at the most an  m120 m170 is WAY TOO MUCH. If you going to get a battery like that or if you want lipos in the futer would recomend these.

At that ROF in such a tight barrel It's gonna be bound for disaster. Then you have to think that metals contract and expand in different temperatures so go figure, sometimes the toleranc eof the bb won't load right into the barrel and then you'll pretty much be SOL.

Be my guest if you want to go for it, but I'm sure the hell not.

i've used 6.01 in winter (gas gun(it sucked))
and no problem besides the complete lack of velocity

Well, gas guns relyu on far less moving parts, and zero actual moving parts to directly accelerate the shot. I have a 6.03 in my custom Beretta, and it's still never jammed, even after being rolled in clay-silt mud at Plastic BLizzard II.

Never said it wouldn't work, just meant you're taking one hell of a chance that could end up in you spending more money.

if you read what we're telling you its not the barrel you have to worry about but the bb's you put down it.  just one slightly misshapen bb will ruin your day.
You are not special. You are not a beautiful or unique snowflake. You're the same decaying organic matter as everything else.

Lets put it this way if you shooting on automatic at lets say 1000 rpm and one bb gets stuck in the barrel, what do you think will happen? The other 50 shots going to hit the stuck bb and warp that $50 barrel. 6.03 is plenty.

1,000 RPM is a bare minimum. However, with a 12-volt, we'll assume he'll be closer to about 900, because his magazines will misfeed consistently, even if his gun's cycling at 1,600.

Put it this way:
I do incredibly stupid things with my gun. THings that most people consider over-the-top.

Chavez says I have a habit of overengineering my guns to ridiculous extents.


If I'm saying this isn't a good idea, chances are, it's an extremely bad idea. You WILL have problems running any large battery of ANY kind in a 6.02 or tighter barrel. It's not a question of how well you clean it or what kind of ammo you use, but a question of whether or not you pull the trigger once it's together and not suffering from structural damage.

You wanted to run this by us. Most of us are five-plus year veterans of the sport, many of us having been building guns since the beginning of that.

We don't want to limit you, or try to get you to put together a mediocre gun because we're jealous. We love to see obnoxious guns pushing the limits of convention.

But this is pushing the limits of common sense.


I'm not knocking you, 1Shot, just imparting the wisdom that has earned me a gun that will shoot 395FPS and high-20 RPS performance all day. THere are MUCH better, safer ways to get good accuracy than using a 6.01mm barrel.
FOr example, switching to TSD Tactical pellets. COnventional rounds are milled to roughly 5.89mm for safety and clearance. TSD rounds are milled and polished to 5.94.

Trust us, man, you'll thank yourself later. A lot. THe 6.03 will give you awesome accuracy, and won't need to be replaced if you accidentally fire it more than six times without swabbing it.


I believe the KWA comes with high-grade wiring. I know that the CA comes stock with Si-core wires.

Or, at least, they did back when they cost $550 for an M4.
